*///set of properties and explanation
/* In order to fully use the capabilities of the hardware there is a need for extra
properties : we will define the following enhancement
- usage mode : when on this allows better management of the devices
This is a boolean with 0 = kAOAUsageModeStandard, and 1 = kAOAUsageModeExpert
- Boot beep control : when in expert mode this allow separate control of the boot
beep : volume between 0 or 7. Otherwise boot beep level is done by the adjustement
of volume an mute
- iSub : this allow the detection and control of an iSub : it corresponds to a
structure boolean : present or not/ float 0..1 volume (when active)
- Physical outputs : allow to get the number of physical outputs for separate
control . Each physical output is describing itself by different characteristics
- relative volume : this is between 0 and 1 : it is then translated to
0 -255 to allow fine control of the
- absolute volume : this is equal to system volum * relative volume
- mute state : tell if the input is mute or not
- mute dependancy : index of output that is linked to that one : for
example
- speaker : gives either a generic speaker or if an Apple one allow
it
- Output Effect : this is a dictionnary with Bass, Treble, EQ
EQ is given as a structure of
- Every stuff is passed as CF data
- Input effect
- when the plugin loads the PLugin save Preferences with each of these values for a user
